Organic matter polluted wastewater photochemical degradation reactor single-tank throughput expansion method

Abstract

The invention relates to an organic matter polluted wastewater photochemical degradation reactor single-tank throughput expansion method, and belongs to the technical field of wastewater treatment. A scheme adopted in the invention aims to completely solve the problems comprising unsatisfactory microwave energy utilization condition, small reactor single-tank throughput, insufficient internal liquid circulation intensity and the like in the prior art. The scheme mainly comprises the following steps: wrapping an electrodeless ultraviolet lamp with a metal cage in a quartz tube, communicating a waveguide tube with the inner cavity of the metal cage, and constructing a microwave weak-irradiation air space or a microwave zero-irradiation air space between the outer wall of the metal cage and the inner wall of a reactor; placing the quartz tube in the upper portion area in the wider cavity tube of a hanging vertical upside-down horn-shaped member positioned in the reactor in a hidden manner; and extending and expanding the dimension of the microwave weak-irradiation air space or the microwave zero-irradiation air space in the reactor in a three-dimensional direction. The method provided by the invention comprehensively solves the series of problems.

Description

technical field [0001] The invention relates to a method for expanding the processing capacity of a single tank of a photochemical degradation reactor for organic polluted wastewater, belonging to the technical field of CO2F wastewater treatment. Background technique [0002] Microwave photocatalytic degradation treatment technology, as an effective harmless treatment technology for industrial wastewater containing organic pollutants, has developed rapidly in recent years. [0003] Regarding the microwave photocatalytic degradation technology, as an example, refer to the Chinese patent application with publication number CN102260003A. [0004] The Chinese patent application with the publication number CN102260003A uses microwaves as the excitation source to excite the electrodeless ultraviolet lamp to emit ultraviolet rays, and irradiates the suspension mixed with photocatalyst titanium dioxide inside the liquid. The electrodeless ultraviolet lamp is shrouded and protected b...
